"Long Engine Life Starts With Reiff" We manufacture FAA approved aircraft engine preheat systems and related products to improve your safety, help your expensive engine last longer, and simplify your winter flying. And don't forget that a preheated engine means shorter run-up time and that saves you gas. Our preheat system is the first choice of mechanics and aircraft owners all over the world, such as Embry-Riddle Aeronautical University and the US Air Force and Naval Academies, as well as aircraft manufacturers like Cirrus and Mooney. Why? Because it's the best system in the world. We are the innovation leader who has set the new standard. Unlike competitive systems, we heat ALL your cylinders and don't use your CHT ports to do it - no messing around with expensive Rube Goldberg arrangements to allow your CHT gauge or engine analyzer to work.
